MATRIX.

Specification of Letters Patent.

Patented Jan. 11,1916.

Application filed May 15, 1915. Serial No. 28,257.

To all whom it may concern:

Be it known that 1, DAVID Pn'rnr-Pnmrnno, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and useful Improvement in .iiatrices, of which the following is a full, clear, and exact description.

My invention relates to matrices adapted for use in circulating matrix type bar casting machines. In such machines the matrices are stored in magazines from which they are released by the operation of finger keys. These machines contain mechanisms which act automatically to compose the released matrices into lines; to justify said lines; to present the justified lines to the casting mechanism by which a type bar is cast which bears on its edge the combination of characters on' the assembled matrices; to disintegrate said lines; and finally, to distribute the component matrices to their respective magazines, and also means for moving the matrix lines along from one to another of these mechanisms. These matrices necessarily vary in thickness according to the width of the characters which are depressed in one vertical edge of each matrix.

In order that the matrices may cooperate properly with the distributing mechanism, it has been found necessary to form a. recess in one side of each matrix in order to thereby produce a combination web in which the distributing combinations may be formed. These webs must be of the same thickness on all matrices, regardless of the thickness of the matrices themselves, and obviously, this requires that the web producing recesses be of different depths on matrices of different thickness. These necessary differences in the matrices have required that some of the matrix manipulating mechanisms in the machine be more complex than would be necessary if the matrices were all alike as to thickness. This is particularly the case in connection with the so-called assembler throat to which the matrices are delivered from the gatherer belt and through which they pass to the action of the composing mechanism. This throat has heretofore been formed so as to be variable in width, in order that matrices of different thicknesses, either in the same font or different fonts,could pass through and be properly handled as they passed or afterward.

The present invention relates to matrices,

which, while of different thickness and formed with webs of like thickness, produced by recesses of different depths, have such parts so arranged thereon with respect to the character depressions and the path traveled by the matrices during composition, that they facilitate the simplification of the matrix handling mechanism, and not only permit the assembler throat to be made of invariable width, but also to be so made that it will cooperate with said recesses and webs for guiding the matrices properly to the action of the composing mechanism. In a companion case is shown and described such an assembler throat of invariable width, and such adjacent composing mechanism as 1s adapted for cooperation with the matrices which are herein shown, described and claimed.

In the drawing, Figure l is a perspective view of a matrix which embodies this invention, said view showing clearly the front edge of the matrix and that side of the matrix which is the following side while the matrices are being composed, and while the composed line is being moved toward the casting mechanism; Fig. 2 is a perspective view of the same matrix arranged to show its rear edge and that side which is the leading side during composition. Fig. 3 is a per spective view similar to Fig. 1 showing a thinner matrix, and Fig. 4'. is a plan view showing several matrices of different thicknesses in the relative positions they occupy when assembled in line; the arrow below said figure indicates the direction in which matrices travel during composition, and when the composed line is moving toward the casting mechanism.

Each matrix stands upright as it is moved through the machine; and it has near its upper end two cars 10 and 12, which project respectively forward and rearward therefrom. It has likewise two other ears 14 and 15 near its lower end which project respectively forward and rearward therefrom. Each matrix is supported by one or the other of these pairs of cars as it circulates through the machine in which it is adapted for use. It is to be noted that said ears are adjacent to that side of the matrix which is the following side during composition (see Fig. 4), and also that the rear or following faces of said ears are in the same plane as the rear or following sides of the matrices. The location of said ears as stated render them better adapted for cooperation with such composing mechanism, as is shown in said companion case.

In the rear vertical edge of each matrix is an inverted character depression 16. In that side of the matrix which is the leading side during composition, is a vertical recess 17 which extends from top to bottom of said matrix. This forms a web 18 between the thick front and rear edges of the matrix. This web as stated must be of substantially the same thickness on all matrices, and therefore the recesses 17 must be of different depths on matrices of different thickness.

It is obvious that the primary invention may be embodied in matrices which are not formed with ears; but the ears are necessary on matrices adapted for use in some machines, as, for example, those which are organized to support the matrices by means of one or the other pair of ears, as the matrices are moved about in the machine. Also when the primary invention is embodied in matrices having ears, it is not essential that said ears be in the same vertical planes with the webs. But the location of the ears as stated, so that their following faces are flush with the following sides of the matrices, is .arather important minor feature of the invention in its best form, because the following faces of the ears may be finished at the same time as the following sides of the matrices, and the leading face of said ears may be formed and finished at the same time that the groove or recess 17 is finished.

The holes 19 in the webs of the matrices .are the distributer combinations, and these are adapted for cooperation with such distributing mechanism as is shown and de scribed, for example, in Letters Patent No. 921,065, but the described matrix may have any other kind of distributer combination formed in the web which will adapt the matrices for cooperation with other kinds of distributer mechanism.

Having described my invention, I claim:

1. A matrix adapted for circulation in a typographical machine wherein it travels in an erect position sidewise during com position, said matrix having an inverted character depression in its rear edge, and having a vertical groove extending from top to bottom in that side which is the leading side during composition.

2. A matrix adapted for circulation in a typographical machine wherein it travels in an erect position sidewise during composition, said matrix having an inverted character depression in its rear edge, and a vertical groove in its left side extending from top to bottom, and having a smooth right side.

3. A matrix adapted for circulation in a typographical machine wherein it travels in an erect position sidewise during composition, said matrix having an inverted character depression in its rear edge, and forwardly and rearwardly projecting ears, and a distributer combination web, the following faces of said ears and of the combination web being in the same plane and on that side of the matrix which is the following side during composition, and said matrix having in that side which is the leading side during composition a vertical groove extending from top to bottom by which the said web is produced.

4. A set of matrices of which the matrices are of different thicknesses but which have combination webs of the same thickness and which have in those sides which are the leading sides during composition vertical grooves which extend from top to bottom, and are of difl'erent depths on matrices of different thicknesses.

5. A. matrix adapted for circulation in a typographic machine wherein it travels in an upright position sidewise during compo-,

sition, said type or matrix being formed with projecting ears of less thickness than that of its body, and with a distributing web of less thickness than that of its body, said web and ears being located in the same plane and at that side thereof which is the following side during composition.

In testimony whereof, I hereunto" affix my signature in the presence of two witnesses.
